Ever since 2013, the adventures of Rick Sanchez and his grandson, Morty, have captivated the world, making the show one of the most popular of its time.
The titular duo's adventures, thanks to the fact that Rick is the smartest man in the universe with unlimited access to time and space in every conceivable dimension, have literally endless possibilities. Weird things like aliens, parallel universes, and a man turning himself into a pickle have become second nature, almost normal, in the world of Rick and Morty.
This gives fans license to really expand their theories to the truly wild, because nothing is beyond the realms of the possible for Rick and Morty. Some theories absolutely push this rule to its limit, but that's just part of the fun.
At the other end of the scale are the theories that make so much sense that its hard to ever put them in the back of your mind when watching the show. Some are so watertight that it seems impossible for them not to be true. The Rick and Morty fandom over the years have managed to find a good balance between the plausibly bizarre and the bizarrely plausible.
10. It's Set In The Same Continuity As Futurama
There has been no shortage of crossover between the biggest cartoon shows in the past. The Simpsons finally came together with both Futurama and Family Guy in 2014, and Seth MacFarlane's trio of Family Guy, American Dad, and The Cleveland Show all shared a story line in 2011.
Rick and Morty also crossed over with The Simpsons by way of a couch gag in the season 26 episode, Mathlete's Feat. While this scene saw the two crash land in Springfield, it actually raised more questions about the show's relationship with Futurama.
As Morty goes through the portal to an alien world to bring Homer and co. back to life, there is a litter of references to the show based in the 31st century. The Planet Express ship can be seen flying through the background, Morty walks past a Slurm vending machine, and there is a man queuing with a brain slug on his head.
Of course, the timelines don't quite add up since Rick and Morty appears to take place in the present day, but it isn't beyond the realms of possibility that Rick sent Morty into the future to bring the Simpsons back. Maybe the show takes place in the present while Fry is trapped in the cryogenic freezer tube.
